Scientists estimate that millions of species are yet to be discovered and classified, if on 1.5 m or 10% of species have been classified, how many species are left to be discovered?
@scann,
How many 10%'s make 100% (Hint they're additive--that is 10%+10%=20%)?
The the number of species would be the number of known specied times this number.
